Seems like a good shoe so far and looks just like the product images. The sizing is 100% accurate i got a 9.5 and it fit perfectly. Taking a star off for the terribly paper thin insoles in came in as i had to immediately replace those with some third party memory foam insoles. Definitely needs more cushioning out of the box. For the money though i recommend them.
